Hi!

Support for the equivalent of #include has been added to "neos" the
universal compiler that can compile any programming language:

class source_package_import : public
semantic_concept<source_package_import>
{
// types
public:
using data_type = neolib::string;
// construction
public:
source_package_import() :
semantic_concept{ "source.package.import", neos::language::emit_type::Infix }
{
}
// emit
public:
bool can_fold() const override
{
return holds_data();
}
bool can_fold(const i_semantic_concept& aRhs) const override
{
return aRhs.name() == "source.package.name";
}
// emit
protected:
void do_fold(i_context& aContext,
neolib::i_ref_ptr<i_semantic_concept>& aResult) override
{
language::source_fragment file{ data<neolib::string>() };
file.set_imported();
aContext.load_fragment(file);
aContext.compiler().compile(std::move(file));
}
void do_fold(i_context& aContext, const i_semantic_concept& aRhs, neolib::i_ref_ptr<i_semantic_concept>& aResult) override
{
data<neolib::string>() = aRhs.data<neolib::i_string>();
aResult.reset(this);
}
};

You should reconsider that. Some languages use include to compensate
the lack of some better features for the same purpose. languages that
have those better features don't need include and usually haven't.

If I were a Ritchie (pace, Tevye, there is no music), the VERY
FIRST TIME a compilation failed because I forgot a header I'd
have merged all the headers into one and then hardcoded that one
everything.h header into the compiler itself. Problem... SOLVED.

But since some languages use it, to compile programs in that language
you need it.

You also need the equivalent statement in other languages, like import.

Doesn't work for user includes.

Indeed. But if it works for stdio, stdlib, string, math, ctype
and assert, it works all the work it has to.

Yes, we could have the compiler auto include all the standard
headers, but then we lose the ability to improve the backwards
compatibility of standards that require the inclusion of a new
header to enable new nice symbols for new features that used to
be available to the user to use.

I'll take the hit. :-)

That's the way with the standard libraries but modular programming requires something else.
